RAZOR-BLADE HOLDER.

Application filed August 13, 1925.

My invention relates to new and useful improvements in a razor blade holder, and has for its primary object to provide an ex ceedingly simple and effective device of this character which will be compact, strong and durable and relatively inexpensive in. the cost of manufacture.

Another object of the invention is to construct a razor blade holder adapted to hold different styles or makes of razor blades.

A further object of the invention is the provision of a razor blade holder comprising a slotted rod having a notched head on one end with a sleeve or barrel slidably mounted on the rod with the end adjacent the head notched for coaction with the razor blade, said sleeve or barrel being movable in one direction by an actuating knob having threaded connection with the rod.

lVith these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains, may understand how to make and use the same, I will describe its construction in detail, referring by numerals to the accompanying drawing forming a part of this application, in 30 which Fig. 1, is a side elevation of the razor blade holder actuated in accordance with my inven' tion and showing a razor blade therein.

Fig. 2, is a section at the line 22 of Fig. 1, with the rod, head and razor blade in elevation.

Fig. 3, is a section at the line 33 of Fig. 2, with a portion of the rod in elevation and the razor blade shown in dotted lines.

Fig. 4c, is a section at the line 44 of Fig. 3 including a razor blade.

In carrying out my invention as herein embodied, 5 represents a rod exteriorly threaded at one end as indicated at 6 and provided adjacent its other end with a longitudinal slot 7 running entirely through the rod diametrically.

The end of the rods opposite the threads is provided with a head 8 which, if found desirable, may be formed as a ferrule and extending over the rod a suitable distance beyond the adjacent end of the slot 7 and this head has two pair of notches 9 and 10 directly opposite each other and in alignment with the slot through the rod and it is preferred Serial No. 49,928.

tuat these notches extend from the inner edge of the head outwardly relative thereto a short distance less than that between the inner edge of the head and the adjacent end of the slot 7 thereby providing shoulders 11. slidably mounted upon the threaded end of the rod so as to be projected over the inner end of the slot 7 is a sleeve or barrel 12 having notches 13 and 14 directly opposite each other and adapted to align with the slot 7 (35 when the holder is in use which is accomplished by means of the actuating knob 15 having an internally threaded socket for registration with the threaded end of the rod so that as said knob is threaded onto the 7 rod it will engage the outer end of the sleeve or barrel 12 and move the same toward the slot 7. Y

The reference numeral 16 represents a razor blade and where such razor blade is provided with endwise extensions one of said extensions will engage the shoulders 11 while the inner end of the sleeve will project over the other extension and thereby prevent said razor from being accidentally displaced but where the 0 blade is of the double edge variety the blade is placed in the slot 7 so that both edges protrude beyond the outer circumference of the rod and the sleeve or barrel 12 is then moved inward until the inner edges of the notches g5 13 and 14: engage'one end of the blade and force the other end of said blade into engagement with the inner ends of the notches 9 and 10 in the head thereby clamping the blade between the head and barrel.

Of course I do not wish to be limited to the exact details of construction as herein shown as these may be varied within the limits of the appended claims without departing "from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful is 1. A razor blade holder comprising a rod having a longitudinal slot adjacent one end passing entirely through said rod, the op- 100 posite end of said rod being threaded, a notched head on the rod adjacent one end of the slot, a barrel slidably mounted on the rod and having notches at the end adjacent the slot in the rod and means having threaded 5 engagement with said rod to move the barrel toward the slot.

2. A razor blade holder comprising a rod threaded at one end and provided with a longitudinal through and through slot adjacent 11 the other end, a head on the end of the rod adjacent the slot and extending beyond the adjacent end thereof With opposite notches therein aligning With the slot in the rod, a barrel slidably mounted upon the rod and having opposite notches in the inner end of said barrel for registration With the slot in the rod, and an actuating knob mounted on the threaded end of said rod and engaging '1 the outer end of the barrel to force the same toward the slot in said rod.

3. A razor blade holder comprising a rod having a longitudinally extending slot passwith the slot in the rod and terminating inwardly of the same, a barrel slidably mounted on the rod and having notches registering with the slot of the rod and means connected to that end of the rod adjacent the opposite end of the barrel whereby the barrel can be adjusted relative to the head.

In testimony whereof I have hereunto aflixcd my signature.
